Multiple Choice

During the formation of a 4-glucose amylose molecule from four glucose monomers via condensation reactions, how many water molecules are released?

Verified step by step guidance

Understand the concept of condensation reactions: In biochemistry, condensation reactions involve the joining of two molecules with the release of a water molecule (H₂O). This is the mechanism by which glucose monomers are linked to form polysaccharides like amylose.

Recognize the structure of amylose: Amylose is a polysaccharide composed of glucose monomers linked by α(1→4) glycosidic bonds. Each bond formation between two glucose molecules involves a condensation reaction.

Determine the number of bonds formed: To create a 4-glucose amylose molecule, three glycosidic bonds must be formed because the first glucose does not require a bond to be formed—it serves as the starting point.

Calculate the number of water molecules released: Since each glycosidic bond formation releases one water molecule, the total number of water molecules released is equal to the number of bonds formed. For three bonds, three water molecules are released.

Verify the reasoning: Ensure the logic aligns with the biochemical principles of condensation reactions and glycosidic bond formation. The correct answer is based on the number of bonds formed, not the number of glucose monomers.
